Biometric Based Recognition Systems - An Overview

Ahmed AK. Tahir, Steluta Anghelus

Abstract


Biometrics technology is gaining an important role in providing solutions to many issues in different applications that require person identification such as forensic sciences, security, finance, border screening, ministries and government offices. It is defined as the technique of analyzing physiological and behavioral traits such as face, fingerprint, iris, retina, voice, signature, etc., for person identification and authorization. At present, a lot of research work is being carried out to accomplish biometric recognition systems based on different types of human traits. To provide a comprehensive survey, this paper provides an overview of six biometric traits (iris, finger vein, fingerprint, face, voice and signature). The overview will cover acquisition method, preprocessing methods, features extraction methods, classification methods, application area, system evaluation and strength/weakness.
